One such wave is described as breaking on one of these islands with tremendous violence. It appeared at first like a dark line, or low cloud, or, on the horizon. The day was fine though cloudy, and a gentle breeze was blowing; but the sea was not rougher, or the breaker on the coral reef that encircled the island higher, than usual.
